NOTE:
4.
If the word ‘LINEARISED’ and direction arrows appear on this screen then the TTT is using
a second order polynomial to linearise the transducer.
If ‘Menu 2’ is shown, then either:
a)
A ‘SMART’ transducer is not connected.
b)
The transducer is ‘NON-SMART’.
For ‘NON-SMART’ transducers the transducer details can be saved in the TTT for future use.
Transducer details can be edited, deleted or printed. The last transducer used will always be
retained for quick selection.
Follow ‘measure flow diagram’ in SET UP section & refer to TRANSDUCER INTERFACE section.
TIP:
For entry of transducer data, see the ‘USER UNITS’ and ‘USING THE KEY PAD’ sections on
page 11.

This will compensate for torque wrench sensitivity.
13
Power Saving & Power Down
Battery life can be greatly increased from a minimum of 14 hours by making use of power down. If no key is
pressed or measurement reading taken in the specified time, the TTT will enter power down. The following
will be displayed:
SAVING POWER
PRESS ANY KEY TO CONTINUE
The following features should be noted:

The POWER DOWN TIME is set in the SETTINGS, POWER DOWN TIME.

For maximum battery life set POWER DOWN TIME to 1 minute.

To disable the power down feature set POWER DOWN TIME to 0 (zero).

The TTT also enters power down when in a set up menu.

The analogue output will NOT work during power down.
TIP:
Check the zero setting of the transducer on return from power down.
When the battery is low there is approximately 20 minutes of use left. In the measure screen a flashing
battery symbol will be seen in the top right hand corner of the display. In a SET UP menu, the following is
displayed:
WARNING #202
BATTERY LOW
PRESS X
When battery is flat the TTT must be turned off or recharged. The following is displayed:
WARNING #201
BATTERY FLAT
SWITCH OFF AND RECHARGE BATTERY
NOTE:
14
From a very flat battery it may take 1 minute of mains power before the display will turn on.
Limits
Limits can be selected In Measure by pressing
or
.
The target is shown at the top left of the screen and if no limits have been set, the TIME & DATE will be
shown. If limits are available but not selected, ‘↓↑LIMITS OFF’ will be shown.
The limit status is shown in 4 ways:
1.
On the display showing LO / OK / HI next to the torque value (updated at 3 Hz).
2.
On AMBER / GREEN / RED LED’s on front panel (updated at 208 Hz).
3.
On the Serial Port LO / OK / HI is sent before torque value (updated with serial port).
4.
On the Ancillaries LO / OK / HI logic outputs (updated at 208 Hz).
TIP:
The Ancillaries are updated quickly to give a fast response to an external control system.
NOTE:
This difference in update rate may lead to very small differences between the changeover
points.
The LED’s & logic outputs change precisely with increasing torque, and at 0.5% of transducer capacity below
the limit with decreasing torque. This eliminates the logic lines oscillating.
The status of the limits changes as follows:

Limit Operation
Limits follow the transducer input and are not held.
For PEAK MEMORY RESET = MANUAL, Limits status is held until
PRINT / RESET is pressed.
For PEAK MEMORY RESET = AUTO, Limit status is held until after the
auto reset timer has operated.
Limit status is held until after the auto reset timer has operated.
TIP:
When TTT is switched on, the target shown is the last one used.
TIP:
The TTT will automatically change torque units to those set by the limits.
TIP:
Limits can be set up in USER units for operation with transducers programmed with the same
USER units.

TRANSDUCER INTERFACE
The 3 transducer connectors are designed for use with most four wire bridge strain gauge type transducers.
When used with Norbar ‘SMART’ transducers the calibration data will be automatically known.
For ‘NON-SMART’ transducers up to 20 sets of transducer parameters can be stored in the TTT for ease of
use. These can be configured with USER units.
TIP:
Mark ‘NON-SMART’ transducers with their stored ‘T’ number for ease of identification.
Ensure transducer selection switch is in the correct position for the transducer in use. See the TD#1, TD#2 &
TD#3 symbols next to transducer connectors.
TIP:
Press '#' in track mode to show details of transducer in use.
TIP:
If any of the transducer’s parameters are changed i.e. re-calibration of mV/V value, the
transducer’s stored parameters must be edited prior to use. (‘NON-SMART’ only).
Norbar transducers with the following suffix are all suitable for use with the TTT:

PIN 2
Momentary
Switch
The switch must remain active for at least 200 mS. Screened cable is recommended.
Limit Outputs
Pins 3, 4 & 5 are buffered logic outputs intended for Go/No Go control of external equipment.
All limit outputs are referenced to Pin 9 (Digital 0V). All limit outputs are active HIGH & change at 208 times
per second. For more information on limits, see ‘LIMITS’ menu which can be accessed via the ‘SET UP’
menu.
Limit output current, High = -0.8 mA, Low = 16 mA (not for direct control of relays).
18
Analogue Output
The analogue output is designed for connection to a control system. It is a true analogue value, so has a
very fast frequency response of above 10 kHz. The calibration of the analogue output is factory set and not
adjustable, it is not affected by the instrument calibration.
5V
Analogue
Output
Pin 11
2.5V
Pin 12
Pin 13
The analogue output is PIN 11.
If the output is measured against PIN 12 (2.5V) the signal will swing positive for clockwise torque and
negative for anticlockwise torque.
If the output is measured against PIN 13 (0V) the signal will always be positive, with zero torque around 2.5V.
TIP:
Some transducers (Norbar Annular type) will give a negative output change for a positive
torque. This is because they are designed to measure reaction torque.
The output voltage is a function of the mV/V value. The larger the mV/V value the larger the analogue output
voltage. At transducer full scale the analogue output voltage (in volts) is numerically equal to the mV/V value
divided by 2.
TIP:
Find the mV/V value by pressing ‘#’ in the track mode or refer to the transducer’s calibration
certificate.

The analogue output will not operate in power down mode. If using the analogue output
continuously then disable the power down feature by setting to 0 (zero).
The accuracy of the analogue output is +/- 2% of voltage reading. For a more accurate output value the
voltage can be externally scaled against the displayed torque.
Connector Type
15 way female ‘D’ type connector.
19
SERIAL PORT
The serial port is for sending data to a PC or serial printer.
When the TTT is measuring, data can be output on the serial interface automatically when the AUTO RESET
timer operates or when the 'PRINT / RESET' key is pressed. The data can include the measured value, units
of measurement and time/date. Output can also be requested externally via pin 2 (ancillaries connector), see
ancillaries section.

Transmitted data voltage levels are between +5 to +9 volts and –5 to -9 volts.
Configured as DTE (Data Terminal Equipment) and conforms to RS-232-C specifications.
TIP:
If the serial port is not communicating with other equipment try:
a) Check that all serial port parameters on the TTT and the equipment receiving data match.
b) Check that the baud rate is set to the same as the equipment receiving data.
c) Check that the connecting lead is wired correctly at both ends.
d) Check if equipment receiving data requires the units of measurement inhibited or a
leading character.
e) Select CONFIRM at the end of the serial port settings, the TTT will keep sending a ‘TEST
OUTPUT’ message to help fault finding.
TIP:
If the serial output is being overwritten set ‘Output Line Feed’ to YES.
TIP:
If the Serial data is being sent too quickly the printer may not keep up, so data is lost. To slow
down the TTT output change the ‘Line delay’ function.
Pulse Count
When in IMPULSE TOOL or CLUTCH TOOL modes, the pulse count is output on the next line following the
measured value. The pulse count will be output as follows ‘_/\_#=XXXX’. XXXX represents the number of
pulses.
20
Hyperterminal
®
The standard HyperTerminal program found in Microsoft Windows allows the user to view and store serial
output data. For more information see www.norbar.com and select FAQ.
TIP:
Downloading of data can be speeded up by changing the LINE DELAY to 0 SECONDS.
TIP:
To regulate the CONTINUOUS OUTPUT, set LINE DELAY to required time period.
Limits
The serial port will output LO / OK / HI when the limits are being used.
Some software, including the Norbar ‘Torque Wrench Calibration Software’ (Part 37705.XXX), will not accept
LO / OK / HI characters.
To remove LO / OK / HI set OUTPUT LIMITS to ‘NO‘.
